DNA and Protein Synthesis Quiz

What is the primary function of DNA in living organisms?

• To provide structural support to cells

• To store and transmit genetic information

• To transport molecules across cell membranes

• To catalyze biochemical reactions

During transcription, what is the role of RNA polymerase?

• To add a poly-A tail to mRNA

• To splice exons together

• To synthesize a complementary RNA strand

• To unwind the DNA double helix

Which strand of DNA serves as the template during transcription?

• The coding strand

• The non-coding strand

• Both strands

• Neither strand

What is the purpose of adding a 5' GTP cap to mRNA?

• To facilitate RNA splicing

• To initiate DNA replication

• To protect mRNA from degradation

• To convert mRNA into protein

How does alternative splicing benefit an organism?

• It allows for multiple proteins from a single gene

• It enhances DNA replication accuracy

• It prevents mRNA degradation

• It increases the rate of transcription
